Olympia Express - Cremina Piston Installation Tool Kit - 240124Works on all Cremina's from 2002 Present Works on all Cremina SL's from 2020 Present Please note: For Cremina SL you would still need to compress the Spring. For Cremina SL we recommend sending the group head in for service. We don't expect to see any for some years to come. :) For Cremina's without the Spring: Cerini's does offer a rebuild service where you would send in the group head alone. Just unbolt the group head from the machine, pack it well,
